This is description of this part:
The interchangeable single objective holder for Lomo Polam series polarizing microscopes allows a single objective to be installed in place of the standard objective nosepiece.
This holder is compatible with the following polarizing microscopes:
- Lomo Polam L-211
- Lomo Polam L-213
- Lomo Polam LMPR
The microscope models listed above are equipped with a removable 5-position objective nosepiece that can be removed and replaced with this single objective holder. A single-objective configuration has long been a standard solution in polarizing microscopy, and many users still prefer it today.
Simpler models, such as the Lomo Polam C-111 (Latin transcription S-111) and P-111 (Latin transcription R-111), do not have a removable objective nosepiece. Therefore, this holder is not compatible with those models.
Important:
The objective is not screwed directly into this holder. This holder does not have an RMS thread. It accepts objectives that have already been mounted in dedicated centering adapters. These adapters provide the precise objective centering required for polarizing microscopy.
The manufacturer illustrates this holder in Figure 4 of the instruction manual (item 47) and refers to it as щипцовое устройство (shchipcovoe ustrojstvo - pincer device).
Several names are commonly used for this component in documentation and among microscope users, including:
- single objective holder
- single objective mount
- objective holder
- objective clamp
- objective carrier
- pincer holder
- single objective nosepiece
- objective socket
- the English term "single objective microscope nosepiece" is very commonly used, even though it is technically associated with a revolving nosepiece
If you need additional comparison photographs, this database also contains:
- the 5-position objective nosepiece for this microscope model (part number 00798)
- the centering adapter for a single RMS objective (supplied together with the objective as part number 00772)
What is this part needed for?
- if you have a Lomo Polam microscope without any turret
- if your turret or single-objective-holder is damaged
- if you need an additional microscope objective holder
